Description

Technical Field

[0001] This utility model relates to the field of injection molded lunch box technology, and in particular to a stackable multi-compartment injection molded lunch box. Background Technology

[0002] As modern families increasingly demand healthier and more convenient food, the market demand for lunch boxes is growing. Multi-compartment lunch boxes, in particular, are favored for their ability to effectively separate food and prevent flavors from mixing. However, traditional lunch boxes often require multiple stacks for storage or transport. Existing designs are prone to slipping or tipping over when stacked due to structural instability, causing inconvenience in daily use. This is especially true in scenarios such as family picnics or bringing lunch to work, where the stability of stacked lunch boxes directly affects the user experience and food preservation.

[0003] Currently, the stacking design of household lunch boxes on the market mainly relies on simple geometric matching or external auxiliary structures. For example, some lunch boxes use grooves or protrusions on the bottom of the box to physically engage with the opening edge of the upper lunch box, using the friction of the contact surface to prevent slippage. Other designs use a nested structure, achieving initial fixation through the conical fit between the upper and lower boxes.

[0004] The existing stacking design of household lunch boxes generally suffers from insufficient stability. Especially when subjected to external shaking or handling, the stacking method relying solely on geometric matching or friction is insufficient to effectively prevent relative sliding between lunch boxes. This defect causes the lunch boxes to easily shift or even tip over during carrying or storage, which not only affects aesthetics and ease of use, but also causes food leakage or container damage. To address this issue, a stackable multi-compartment injection-molded lunch box is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a stackable multi-compartment injection molded lunch box, which aims to improve the problem in the prior art that the stacking method relying solely on geometric matching or friction is difficult to effectively prevent relative sliding between lunch boxes when subjected to external shaking or handling.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A stackable multi-compartment injection-molded lunch box includes a lunch box one and a lunch box two. The lunch box one is provided with a lunch box lid at the top, and the lunch box lid is snapped onto the top of the lunch box one. A connecting plate is fixedly connected to the top of the lunch box lid. A connecting frame is fixedly connected to the bottom of the lunch box two. The connecting plate is slidably connected inside the connecting frame. A buckle assembly is provided inside the connecting plate.

[0008] The buckle assembly includes a locking ball, which is slidably connected inside the connecting plate and engages with the connecting frame. A limiting plate is fixedly connected to the side wall of the locking ball, and the limiting plate is slidably connected inside the connecting plate. A spring is provided inside the connecting plate, with one end fixedly connected to the inner wall of the connecting plate and the other end fixedly connected to the side wall of the limiting plate. A partition is slidably connected inside the food container, and a positioning assembly is provided inside the partition.

[0009] As a further description of the above technical solution:

[0010] The positioning component includes a positioning post, which is slidably connected inside the partition.

[0011] As a further description of the above technical solution:

[0012] The food container has a positioning hole inside, and one end of the positioning post engages with the positioning hole.

[0013] As a further description of the above technical solution:

[0014] The food container has a limiting groove inside, and a sliding block is fixedly connected to the side wall of the partition. The sliding block is slidably connected inside the limiting groove.

[0015] As a further description of the above technical solution:

[0016] A sliding disc is fixedly connected to the outer wall of the positioning column, and the sliding disc is slidably connected inside the partition.

[0017] As a further description of the above technical solution:

[0018] A pull ring is provided at the other end of the positioning post, and one side of the pull ring is fixedly connected to the other end of the positioning post.

[0019] As a further description of the above technical solution:

[0020] A second spring is fitted on the outer wall of the positioning column. One end of the second spring is fixedly connected to the side wall of the sliding disk, and the other end of the second spring is fixedly connected to the inner wall of the partition.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the connecting plate is slidably connected inside the connecting frame, which drives the lunch box one and lunch box two to be initially stacked. Then, the locking ball in the buckle assembly is engaged with the connecting frame under the action of spring one and the limiting plate, which drives the lunch box one and lunch box two to be firmly connected, thereby enabling multiple lunch boxes to be stacked stably, thus achieving the effect of preventing sliding and tipping during stacking, solving the problem of easy displacement of stacked lunch boxes, and improving stacking stability.

[0023] 2. In this utility model, the sliding block slides inside the limiting groove, causing the partition to move within the lunch box to adjust the space. Then, the positioning post in the positioning component engages with the positioning hole under the action of the spring and the sliding plate, fixing the partition in the adjusted position. This allows the internal space of the lunch box to be flexibly adjusted, thus achieving the effect of adapting to different food storage needs, solving the problem of fixed internal space of the lunch box, and improving the flexibility of use.

[0035] Working principle: When stacking lunch boxes, first, snap the lunch box lid 3 onto the top of lunch box 1. Align the connecting plate 4 fixed to the top of lunch box lid 3 with the connecting frame 5 at the bottom of lunch box 2. Push lunch box 2 to move the connecting frame 5 onto the outside of the connecting plate 4. The connecting plate 4 slides inside the connecting frame 5. During this process, the inner wall of the connecting frame 5 presses against the retaining ball 6, causing the retaining ball 6 to slide inwards from the connecting plate 4. The retaining ball 6 drives the limiting plate 7 to slide synchronously and compress the spring 8. When the retaining ball 6 corresponds to the snapping position on the connecting frame 5, the spring 8 resets and pushes the limiting plate 7, causing the retaining ball 6 to pop out. It engages with the connecting frame 5 to complete the stacking and fixing of lunch box 1 and lunch box 2. When it is necessary to adjust the internal space of lunch box 1, pull the pull ring 16 to drive the positioning post 13 to slide outward of the partition 9. The positioning post 13 drives the sliding plate 14 to slide synchronously and stretch the spring 2 15, so that the positioning post 13 disengages from the positioning hole 11, pushes the partition 9 to drive the sliding block 12 to slide inside the limiting groove 10. After adjusting to the appropriate position, release the pull ring 16, the spring 2 15 returns to its original position and pulls the sliding plate 14, driving the positioning post 13 to insert into the corresponding positioning hole 11, thereby fixing the partition 9.
